Application filed December 5, 1310. Serial No. 595.587.

To (1] L whom it may cones rm" lle it known that I. I'loRAon VIBRAN, atlilZtll oi the United States. residing at State of l\'[assachusetts,have invented certain new and us ful lmprm'ements in Photograph-Filml)evelopmg Devices. ot which My invention relates to a photograph filmdeveloping device. and the oh eet-"of my 111- veloping deviee of simpleconstruction and operation.

My invention consists in certain novel features at eonstructicn o'linyphotograph film developing device. as will he hereinafter tallydeacrihed.

'l v photograph film developing device consists ot a segment of acylinder. having a. eTircular flange or plate at each end, attachedthereto. There is an open space next to thelhoeudls ot the segment atthe cylinder.

Within the segment of the cylinder and seveloped. .irranged opposite thesegment of that of the said segment is a reel earriedon A flexibleapron, hav ng 1th edges or hordersrarsHl The raised horthe. flanges andtheen'daJot the ae mentoit segment. and the apron may eontaet, and theattaehone eud'ot the film to the reel. A

reeeive' my developing deviee .ahove de:

scribed. used, and means are providedto rotate'the reel. to wind thefilm and apron the reel.

By turningthe crank handle the wound. together with the film. inlayerson Referring to the drawings-2: Figure l. a. plan View of 'my photographfilm develop- 1 end ot the segment 2 ing device, with the cover of thetank removed. Fig. 2 is a section, on line 2, 2, Fig. 1. looking in thedirection of arrow (1, same figure, and showing the cover of the tank inposition. Fig. 3 corresponds to-Fig. 1, hut shows the apron and filmwound on the reel. Fig. 4--is a side view of my pho-- togrz'tph filmdeveloping device, looking in the direction of arrow '1), Fig. 3; thetank with its cover in position, are shown in section, and, Fig. 5corresponds to F ig. 3, but shows a. 'n'iodiiied emistrnetion of thefilm developingdevire; the tank. shown in Fig. 3 is not shown in thisfigure.

in the accompanying drawin 1 is a tank i for holding the developingsolution, and into which mytilm develo nng device is placed. The tank. 1is preferably made of metal and of circular shape. and has a detachablecover, l, shown in Figs. 2 and 4:.

.\"l v photograph .tilm developing device Consists of a segment of acylinder 2, preterahly made in one part as a single segment, and havingits open side on the inside o'l the deviee. Within the segment of thecylinder and secured thereto, is a tubular hollow receptacle 3. to ltioselv receiv and hold the lilm 4. see Figs. 1 and 3. The receptacle 3has its inner side open, as shown at 3, see Figs. 1 and 3, to allow thefilm to pass out from said receptacle. The segment 2 has attached toeach end thereof, in this instance near its inner open side. 1 apair ofarms an upper flange (3, and by a pair of arms" 5. a lower flange (3.There is a n opening or space 7.. ee; Figs. 2 and 4. between the upperand the upper flange (i, and an opening or space? between thelower endot' the segment 2 and the lower flange 0. The lower flange 6 has in thisinstance two or more bosses or extensjons (5 thereon. to rest on thebottom of the tank 1. .1\ reel 8, extending between the two flanges.andhaving its axis parallel to that of the segment- 2,

is carried on a. spindle 9, to which it is re- 1 spindle 9 in thisinstance extends at its lower end into and has a bearing in a boss orhearing' 6 on the lower flange 0. The upper end of the spindle 9 extendsthrough an opening in and has a hearing in the upper flange 5. The upperend or the spindle i) also extends through an opening in the cover 1'.A. detachable handle 10 secured upon the upper end of the spindle 9 torotate the same, and with it the reel 8.

A fiexible apron 11 has its edges or borders l1 raised above itssurface, and said raise borders or edges 11 extend Within the spaces 7and 71, between the ends of the segment. 2 and the fianges G and 6, seeFig. 2. One end of the flexible apron 1 is attached to the reel 8. Thereel 8 is provided with suitable means, shown at 8'', iii 1, for attaching the end of the film thereto.

In Fi 5 is shown a modified construction of my photograph lm developingdevice. In said figure, which corresponds to 'Fi 3. exce t the tank 1 isnot shown in this figure, thefilni developing device is of elongated oroval sliape,-having the elongated or oval shaped upper flange 6 with.rounded ends. i

' In Fi 5, the same figures of reference are used as in the otherfiguresv for similar parts, except in the case ot the G and theconstruction and operation of the partsare the same as already describedin connection with the other figures. modified construction shown in Figh, a longer apron It may he .used, and also a longer film.

The operation of-my photograph film developing device will be readilyunderstood by those skilled in the art. My device is intended for timedevelopment. The method of proceeding is to remove the device from thetank, and having theapron in layers wrapped around the outside of thesegment 2, and the reel 8, as shown in Fig. 1, the raised borders- 11':of the apron 11 extend ing into the open spaces 7v and 7, between theendsof the segment 2 and the flanges:

6 and 6, the apron contacting with the face of the segment, then thetank being filled with the developing solution, the exposed film roll tobe developed is taken, and

the free end of the black paper covering is unwound from the loose'endof'theflfilm,

Which is fastened to thepaper covering by a ,gumme d surface, in theusual way. The

film 4 is inserted through the opening in the flange of the' devic andplaced in the re ceptacle 3, and the free end placedin the space underthe bar 8 on the reels, assh'own in Fig. 1.,to project out therefrom, asshown in Fig. 1. The device is then placed in the tank 1, containing thedeveloping solution,

and the cover 1 placed thereon, and the handle 10 on the spindle 9, l in2, and the. handle 10 turned In the the direction of movement of thehands of a clock; The segment, the flanges, and the film receptacle,remain stationary, while the reel beinglurned to draw the flexible apronfrom around the segment and Wind it upon the reel, with the film drawn.from the roll and transferred between the layers of the apron. Thespindle oi the reel may then he removed, and the hole closed in thecover, and the development proceeded with, by reversing the tankendu'ise occasionally.

It will he understood that the details of construction of myimprovements in photograph film developing devices may be varied ifdesired.
